If the fetal monitor demonstrates a specific pattern, which action would the nurse perform first?

Choice A rationale Preparing for a vaginal delivery is not the first action to perform based on a specific fetal monitor pattern. The initial step is to identify the cause of the non-reassuring pattern and attempt to correct it with less invasive measures. Preparing for delivery is a more advanced intervention and is considered only after other interventions, such as changing maternal position, administering oxygen, and providing intravenous fluids, have failed to resolve the fetal distress pattern. Choice B rationale Administering oxygen at 3 liters via nasal cannula is a supportive measure to increase fetal oxygenation. However, it is not the first action. The most immediate and effective first step is to improve uterine blood flow and placental perfusion by changing the maternal position. Decreasing pressure on the vena cava and aorta is a more direct way to improve oxygen delivery to the fetus than administering oxygen to the mother. Choice C rationale Turning the client or asking them to turn on their side is the first action. This maneuver relieves pressure on the maternal vena cava and aorta, which can be caused by the gravid uterus. By improving venous return and cardiac output, this position change directly increases blood flow to the placenta. This enhanced placental perfusion often corrects non-reassuring fetal heart rate patterns, such as late decelerations, by improving oxygen delivery to the fetus. Choice D rationale Performing a vaginal exam to assess for the umbilical cord is an important assessment, but it is not the first action. While a vaginal exam is necessary to rule out a prolapsed cord, especially with sudden changes in the fetal heart rate, it should be done after attempting the less invasive and immediate intervention of changing the client's position. Position change is a quick and non-invasive way to improve fetal oxygenation and is the priority initial step.
